We look at the division of 42133791 by 488 
Let's see how many times 488 fits into 42133791.

Let's proceed to step 1:
When dividing 4 by 488, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 488

Moving on to step 2:
42 divided by 488 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 488

On to step 3:
488 goes into 421 0 times with a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 421 and we're left with 421.
Grab the next digit (3) from the dividend, add it to 421, then carry on: 4213 / 488

Moving on to step 4:
If we divide 4213 by 488, we get 8 and a remainder of 309.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 3904 from 4213 to get 309.
Bring next digit (3) of the dividend behind the 309 and repeat the process: 3093 / 488

Going ahead to step 5:
The number 488 fits into 3093 6 times, leaving a remainder of 165.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 2928 from 3093, we get 165.
Take the next digit (7) from the dividend and append it to 165, then repeat: 1657 / 488

Step 6:
The number 488 fits into 1657 3 times, leaving a remainder of 193.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
The remainder is 193 after subtracting 1464 from 1657.
Grab the next digit (9) from the dividend, add it to 193, then carry on: 1939 / 488

Advancing to step 7:
When dividing 1939 by 488, we get 3 with a remainder of 475.
Put 3 as the next digit of the answer. 
Result so far: 8633.0
If we subtract 1464 from 1939, we get 475.
Bring next digit (1) of the dividend behind the 475 and repeat the process: 4751 / 488

On to step 8:
488 can be fit into 4751 9 times, resulting in a remainder of 359.
Record the quotient 9 as the next digit in the result. 
Result so far: 86339.0
The remainder is 359 after subtracting 4392 from 4751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 9:
3590 divided by 488 is 7 with a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 86339.7
If we take 3416 away from 3590, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 10:
488 can be fit into 1740 3 times, resulting in a remainder of 276.
Use 3 as the next digit of our solution. 
Result so far: 86339.73
Subtracting 1464 from 1740 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
488 can be fit into 2760 5 times, resulting in a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 86339.735
Subtract 2440 from 2760 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
488 goes into 3200 6 times with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 86339.7356
If we take 2928 away from 3200, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 13:
If we divide 2720 by 488, we get 5 and a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 86339.73565
The remainder is 280 after subtracting 2440 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
488 can be fit into 2800 5 times, resulting in a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 86339.735655
If we subtract 2440 from 2800, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 86339.735655, with a leftover of 3.6e-05.
